.To @ZZ whom t mja/y concern:

Be it known that we, THoMAs C. OCT'IGAN and WILLIAM PEAoooK, of the city of Chicago, in the county of Cook and State of Illinois, have invented cert-ain new and useful Improvements in Horseshoes; and we do hereby decl-are that the following is a full, clear, and exact descriptionlthereof, reference being had/to the accompanying drawings, and to the letters of reference marked thereon, which form a part 0f this specification.

This invention relates to improvements in horseshoes; and the invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure l is a top plan view of a horseshoe containing our improvements. Fig. 2 is a bottom plan view thereof.. Fig. 3' is a transverse sectional view on line 3 3 of Fig. 2. Fig. A is a view of a fragmentary section on line t 4 of Fig. 2. Fig. 5 is a central longitudinal section of the shoe shown in Fig. 2. Fig. 6 is aview of one of the rear ends of the body of the shoe. p

As shown in said drawings, A designates the curved body of the shoe, which is provided on its lower surface with two continuous downwardly-extending flanges or calks A A2, forming between the same a channel A3, extending around the shoe on the under surface thereof. One or both of said calks may be longitudinally corrugated, and, as herein shown, the outer calk A is so formed. The corrugated form ofV iiange or calk A greatly increases its bearing surface, and therefore its adhesive force, upon the roadway. The inner calk or flange A2 is made tapered, as shown in Figs. 3 and 5. Outside the outer flange or calk in the body of the shoe are located nail-holes @,'through which the nails for attaching the shoeto the hoofl of the horse are passed. Vithin said channel i is seated a narrow rubber pad B,which entirely fills the channel and projects a slight distance beyond the margins of the flanges or calks A A2 to form part of the tread-surface. The ends of the rubber pad at the heel of the shoe are joined by an integral transversely-arranged rubber bar B', which is made of considerable width from front to rear of the shoe to insure a rm hold of the shoe on the roadway toprevent slipping. Said bar is curved between its ends toward the toe of the shoe and` has the general form of an arch in plan view. The purpose of so forming the connectingbar B is to permit the shoe to be made narrower or wider, as circumstances may require, when the shoe is being tted to the horses foot, it being the intention that said shoe shall be fitted when cold. By reason of the forward curvature of the central part of the connecting-bar said bar will be bent inwardly and assume a greater curvature when the heel of the shoe is made narrower, and vice versa. The bottom surface of the pad comprising -the parts B B' is roughened, as indicated in Fig. 2, so as to insure the pad taking firm hold upon the roadway. Said connectingbar is made of greater ,depth than the depth of the shoe at the toe thereof, the difference in depth being vapproximately one-quarter of an inch, whereby the upper surface of the shoe is forwardly inclined.

The body of the shoe A is provided on its Vupper surface with a rabbet Ct, which is filled s with a body of rubber B?, which is ilush with the upper surface of the shoe radially outside of said rabbet. Said body of rubber B2 is joined integrally with the pad, consisting of the parts B B', by means of integral connecting-bonds b, extending through openings a2 in the body of the shoe, from the upper to the lower side thereof, as clearly shown in Figs. 3 to 6, inclusive. The rubber is applied to the several parts of the shoe and molded thereupon in any suitable manner to the shape shown, said rubber filling the channel A3 and rabbet ct' and passing through the connecting openings a2 from one side of the body of the shoe to the other to connect the rubber on both sides of the shoe. The rubber is thereafter subjected to a vulcanizing process to suitably toughen the same.

The rear ends of the body of the shoe are provided with odset parts A5 A5, which are embedded in the body of the rubber constituting the connectingbar B'. Said ol'set parts or projections taper gradually from the upper surface of the body of the shoe, as shown in Fig. l, to give the required strength at this part. Said extensions are located slightly below the level of the body of the shoe, and at the junction of the same with the body of the shoe, within the rear ends of the IOO groove A3, are formed oblique oifset surfaces or shoulders a3, as shown in said Fig. 4. Such oblique offset surfaces tend to prevent the rubber pad from slipping backwardly in the groove A3. The corrugation of the rim A also aids to prevent longitudinal displacement of the part of the pad occupying the groove A3. Furthermore, it will be observed that the rear ends of the extensions A5 converge from their points of connection with the body of the shoe and are closer at their rear than at their front ends.4 Said extensions being embedded in therubber of the connecting-bar serve to prevent said bar from shifting rearwardly, and thereby also aid to hold the pad as a whole in place on the shoe.

As before stated, the connecting-bar B is made deeper than the shoe inl advance of the same, and the projections A5 of the body of the shoe, at the heel thereof, are offset above the tread-surface of the flanges or calks A A2, so that below said projections is provided a large body of rubber, which receives through said offset parts the weight brought upon the heel of the shoe. The heel or tender part of the foot rests upon the yielding connectingbar B and the rear quarters of the hoof of the foot rest on the rear ends of the unyielding metal body-of the shoe. When the weight of the horse is brought upon the shoe, lthe part of the connecting-bar below the offset parts A5 is compressed until the tread of the calks in front of the connecting-bar comes in contact with the ground. As the rear quarters of the hoof rest upon the unyielding rear ends of the body of the shoe the weight of the horse is transmitted therethrough to the roadrway, and as the connecting-bar is depssed with the rear end of the body of the shoe upon the compression of the lower part of said bar in the manner described it will be seen that undue pressure is avoided on the heel of the horse.

It will be understood that the weight of the animal when brought upon the shoe is transmitted to the roadway through the calks of the shoe, the pad B, occupying the groove between the calks, yielding until contact of the calks with the roadway is effected. The purpose of the pad B is to prevent the animal Afrom slipping.

In the event of the heel being excessively tender the parts can be so arranged that no appreciable pressure need be brought thereon when the weight of the horse is brought upon the shoe. Moderate pressure of the heel on the connecting-bar even in the case of a tender heel is not, however, a serious objection, as

, the bar yields to such pressure. In tting the shoe to a healthy foot the frog will desirably be made to bear with some pressure upon the connecting-bar, whereby the pressure transmitted to the central part of said bar will cause the bar, to adhere more firmly to the roadway, and thus prevent the shoe from slipping.

The body of rubber occupying the rabbet portion of the upper surface of the shoe, as well as the upper surface of thc transverse bar B', will desirably be protected by a canvas or like covering. Said body of rubber when the canvas is placed thereon will desirably extend flush with the extreme upper surface of the shoe, so that the rigid unyielding part of the shoe when fitted upon the foot may be placed at once against the hoof and secured firmly thereto.

The body of the 4shoe will in practice be formed .from steel between suitably-shaped dies by a forging process, and the rubber constituting the pad and that overlying the footsurface of the shoe will be molded on the shoe in a suitably-constructed mold in a manner familiar to persons acquainted with this art and the rubber thereafter vulcanized.

From the foregoing it will be noted that at the rear end of the shoe there are no metal parts to come into contact with the roadway or the foot of the horse, so that the heel of the footis relieved from pressure such as would occur if the metal of the shoe were continued past the connecting-bar at the levels of the tread of the shoe and the foot-surface thereof. In our construction the parts of the shoe which receive the rst pressure when the foot is placed upon the groundto wit, the rear ends of the shoe--are yielding parts and relieve the horse of concussions and jars, while in a construction where the metal of the shoe is exposed to the extreme ends thereof said metal parts rst strike the roadway and transmit practically the entire jar or concussion to the horse. Moreover, in a shoe having a connecting-bar, as herein shown, and having metal parts which are exposed to the extreme end of the shoe the adhesion of the bar to the roadway would be slight as compared with our construction. j
